Member of Technical Staff
San Francisco, CA · Full-time · In-person
For exceptional builders who don't fit in a box
Former founder? Research engineer? Generalist who's been the secret weapon on every team you've joined? This is the role. Member of Technical Staff means one thing at Sourcerer: you can take an impossibly ambiguous problem — "underwrite any supplier in China," "make an agent negotiate a purchase order" — and come back with a working system.
You'll work across everything: agents, data infrastructure, product, and whatever the mission demands this month. The ceiling on this role is wherever you take it.
What you'll own
Whatever matters most right now — agent workflows, search and scraping infrastructure across a dozen-plus countries, underwriting models, customer-facing product
The full loop — prototype fast, prove it with real customers, then harden it into production
Your own trajectory — MTS here has grown into engineering leadership, AI leadership, and staff-level IC paths. The role becomes what your work earns.
Who we're looking for
Exceptional technical ability — we care about what you've built, not how many years you've existed
Serious experience with modern AI tooling (LLMs, agents, evals) and/or hard systems engineering
Maximum agency: you find the problem, you solve the problem, you tell us about it after
You want the earliest seat possible at a company that already has real revenue and real enterprise customers
What you get
Competitive salary + early-stage equity calibrated to what you bring
Full benefits (health, dental, vision)
The most leverage-per-person you will find anywhere: small team, huge market, direct line to founders and customers
